Abstract
【解決手段】低密度ポリエチレン(A)と、エチレン酢酸ビニル共重合体(B)と、充填剤(C)と、発泡剤(D)と、架橋材(E)とを含有する樹脂組成物を発泡させた樹脂発泡体aであって、低密度ポリエチレン(A)とエチレン酢酸ビニル共重合体(B)との質量比が(A)/(B)=95/5〜90/10である樹脂発泡体aとする。
【選択図】図1
Description
(1)(実施例)および(比較例)に使用した主な材料
・低密度ポリエチレン(A):上海石化有限公司社製 低密度ポリエチレン(LDPE)
・エチレン酢酸ビニル共重合体(B):北京燕化高新技術有限公司社製 エチレン酢酸ビニル共重合体(EVA)
・充填材(C):浙江菱化有限公司社製 炭酸カルシウム(CaCO3)
・発泡剤(D):浙江海虹控股有限公司社製 アゾジカルボンアミド(AC)
・架橋剤(E):上海石化有限公司社製 ジクミルパーオキサイド(DCP)
(2)(実施例)および(比較例)の樹脂組成物の組成
表1に実施例および比較例の樹脂組成物の主な材料の組成を示した(表中の各値は質量部を表し、充填材(C)、発泡剤(D)、架橋剤(E)の値は低密度ポリエチレン(A)とエチレン酢酸ビニル共重合体(B)の合計質量を100質量部としたときの質量部を表している。)。また、表1には示していないが、実施例1〜3および比較例1、2共に炭酸アンチモン(Sb2(CO3)3)を低密度ポリエチレン(A)とエチレン酢酸ビニル共重合体(B)の合計質量100質量部に対し1.8質量部添加している。
